S-94081A716 5/16"-18 x 3" Titanium Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional strength-to-weight ratio with Grade 5 Titanium construction, providing 130,000 psi tensile strength for demanding applications without adding unnecessary bulk
• Superior corrosion resistance inherent to titanium alloy, ensuring long-term reliability in harsh industrial environments
• Optimized torque transmission through the external hex drive and 1/2" head width, allowing for secure installation with standard tools
• Reliable thread engagement with Class 2A thread fit and coarse UNC threading, enabling faster assembly and reduced cross-threading risks
• Partial threading design providing unthreaded shank section for enhanced shear strength in structural applications
• Consistent performance backed by Rockwell C36 hardness rating, maintaining dimensional stability under heavy loads
• Global compliance assurance with RoHS 3 and REACH regulations, meeting international environmental and safety standards

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Grade 5 Titanium hex head screws deliver exceptional performance where weight reduction and corrosion resistance are critical. The 5/16"-18 UNC coarse thread configuration ensures rapid assembly in materials ranging from aluminum to high-strength composites, while the partially threaded design provides maximum resistance to vibrational loosening in dynamic load environments. The external hex drive with 1/2" head width offers superior torque transmission during installation, preventing tool slippage and ensuring proper clamp load distribution. These titanium fasteners are particularly valuable in aerospace, marine, and chemical processing industries where their combination of 130,000 psi tensile strength and lightweight properties solve critical engineering challenges involving weight-sensitive assemblies exposed to corrosive elements.
